Heating and cooling

Government ministers in the UK are considering introducing electricity bill discounts for people who have heat pumps.

Buildings and infrastructure

ABC News in Australia has a fascinating and report about Pacific Islands, including Samoa and Tuvalu, where residents are building huge walls along coastlines to hold back rising seas. In one case, the walls are made from rocks shipped from Dubai. However, studies indicate that sea walls generally have limitations when it comes to holding back the worst storm surges and climate change-exacerbated flooding.
